Default Value

This testvar’s default value is computed dynamically and may not always be the value below. Please see the testvar’s description for details.



If the router supports different MSS Clamping values for the inbound and outbound directions, the expected inbound IPv6 MSS Clamping value can be adjusted using the testvar ipv6MssClampingInValue. If this parameter is set to the keyword default, CDRouter will automatically compute the expected inbound IPv6 MSS based on the LAN MTU setting. If not specified, CDRouter assumes that the MSS Clamping value for both the inbound and outbound directions is the same, as specified by the testvar ipv6MssClampingValue.

This testvar was added in CDRouter 9.1
